After tilting back display, we get this..
So we need a bezel. But first, I used two 1" post sleeves and two 1-1/4" #6 screws to slant display back.
Also, I used two slightly longer screws for the bottom of display mounting. I just used two nuts as washers (in pic) the originals were too short to grab enough.
But first we need to drill two new mounting screw holes for bottom of display, exactly 1/4" above the original hole (I epoxied the old holes).
I removed the plastic display cover. It's not needed and dirt gets in there which will force you to remove display to clean it out. Just carefully push it out with you fingers. Clean off any residual glue that remains so there is a nice flat surface to glue bezels to.
The two top screws with sleeve posts can be marked after you set display in place with lower mounting screws. I carefully marked the hole location with a scratch-all and drilled out some wood for screws. *CAUTION* Do not drill through panel !!
I also repositioned the speaker light rings and trimmed the speaker mesh to clean things up around the side bezels we are going to install. You need to cut some zip tie straps to do this, so get a bag of 4" tie straps at hardware store for this project.
Now, get some thin Polystyrene Plastic Sheet and some plastic friendly black paint.
Now you need to measure and cut out the three bezel pieces. (Sorry. I forgot to write down measurements.)
Then spray paint both sides..
I used a hot glue gun to glue the plastic bezel pieces to wood ledge of slot where display window was installed.
Now I just used Gorilla tape to tape top bezel to display mounting bracket and around each corner.
Here is the finished result. Awesome sharp image that pops!!!! No light blead from back box or speaker lights. Fit and finished!!
Now keep in mind that the display opening is a little too small for the display. The bottom mounting holes that were drilled 1/4" above the originals is key here! Any higher and too much display top gets cut off. Any lower and too much bottom gets cut off. This is as perfect as you can get it. I suspect that the display controller is not functional for adjusting the screen positions because it's a Linux variant OS and display drivers are limited. So this is the best we can do. Some could enlarge the display hole 1/4" if they have a router. I don't have one or I might have done it. But I'm 6'3" tall and the top display scores still gets slightly cut off, but it did before I moved it. No biggy though.
** These mounting bracket slots (circled in red below) should also be covered with Gorilla tape or light will shine through these slots and bezels may not 100% block it all. There are four locations to tape these shut.
* Also, make sure when mounting the display to use the mounting holes shown, or display will sit too high!
